PIPE-VALVE FOR ORGANS.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed September 27,1905. Serial No. 280,273.

To all whom it may concern:

Be it known that I, JACOB BINNIG, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Pipe-Valves for Organs, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

Pipe-valves are commonly made of wood. One disadvantage inherent in a pipe-valve thus constructed is that the swelling and shrinking of the wood due to changes in the humidity of the atmosphere is apt to cause the valve finally to leak. My invention aims to avoid this objection by providing a metallic valve in which the only non-metallic part is the flexible diaphragm which is commonly employed in these structures.

I will first describe some embodiments of the invention and then point out the novel features of the invention in the appended claims.

In the drawings, Figure 1 is a vertical section through two pipe-valves embodying my invention. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a section on the line 00 ac, Fig. 2. Fig. 4 is a vertical section through another embodiment of my invention. Fig. 5 is a similar section, showing still another embodiment of my invention. Fig. 6 is a view to the left of lineyy, Fig. 5. Fig. 7 is a detail hereinafter referred to.

Referring first to Figs. 1, 2, and 3, 3 designates a wind-chest from which the pipes 4 of the organ are operated, and 5 designates generally a pipe-valve which controls the admission of wind from the wind-chest to the pipe. The wind-chest illustrated in Fig. 1 is made of metal and is surmounted by a member 6 on which the pipes 4 rest, as usual, said member being provided with a passage 7 leading to each pipe. In Fig. 1 I have shown two such members 6 arranged above the wind-chest, each one of w ch supports a row of pipes 4, though this arrangement is not essential to the invention. The pipe-valve herein illustrated is of that type in which the diaphragm is situated between opposite walls of the valve-chamber and divides it into two compartments, and the part forming the air-supply passage projects into the valvechamber and terminates in a valve-seat against which the diaphragm rests. A valve of this type is shown in my former patent, No. 784,203, dated March 7, 1905. In the embodiment of the invention shown in Fig. l the diaphragm is designated by 8, and it extends across the valvechamber, dividing it into two compartments 9 and 10. The valve-chamber is preferably formed of two parts, between which the edge of the diaphragm 8 is clamped. One part is shown as a ring 11, which is secured in any suitable way to a backing-piece l2, and which has an outwardly-projecting flange 13, and the other piece is shown as a cap member 14, the walls 15 of which fit over the flange 13. The cap is preferably made detachable from the body portion. The edges of the diaphragm, 8 are confined between the walls 15 of the cap and the fiange 13. The air-supplypassage through which wind is admitted from the wind-chest to the valve is in the shape of a tubular member 16, which is secured in any suitable way to the backing-piece 12, and which projects into the valve-chamber and terminates in a valve-seat 17 against which the diaphragm 8 is seated, said valve-seat being situated between opposite walls of the valve-chamber. 18 designates a pipe leading to any suitable pneumatic mechanism (not shown) by which the pipe-valve is operated. 19 designates a port leading through the backing-piece 12 and communicating with the duct or passage 7, said port and passage constituting the communication between the pipe-valve and the organ-pipe 4. The cap 14 may be held in place in any suitable way, and in Fig. 1 this is accomplished by means of a suitable retainer 20 which is preferably more or less resilient. The retainer herein shown is in the form of a spring-finger, which is bent to form a stem that is secured to and projects from the member 6, the resilient portion of said finger engaging the cap and holding it in place. The backing-piece 12 for each valve might be separate from that for any other valve, but preferably a single plate will extend the full length of the for each valve will be secured thereto. In this embodiment of my invention the rings 11 and backing-piece 12 constitute the body of the valve and the entire valve is composed of the valve-body, the cap, and the port 6 and the various rings 11' diaphragm which is confined between the valve-body and cap.

In the embodiment shown in Fig. 4' the wind-chest 30 is made of wood instead of metal, and the pi e-valve, although made of metal, has a sligIl from that shown in Fig. 1. In this embodiment the valve-body 110 is shaped to present an outwardly-projecting flange 130 and the stem 31, which enters an aperture in the side wall 32 of the wind-chest. Extending through the stem is a neck or tubular member 160, which forms the air-supply passage, said neck terminating in a valve-seat 170 againstwhich' the diaphragm 80'seats, said tubular member projecting into the valve-chamber so as to bring the valve-seat between opposite walls of said chamber. The cap member of the valve is designated by 140, and the walls or flanges 150 thereof overlie the flange 130, and the edges of the diaphragm 60 are confined between the flange 130 and the walls 150. The cap is provided with the foot portion 34, which overlies the side 32 of the valve-chest, and said cap is held in place by means of suitable screws 35, which pass through the foot portion. In this construction the cap 140 serves to hold not only the diaphragm in place but also to hold the valve-body in the wall of the wind-chest. The stem 31 of the valve is provided with a port 190, which communicates with a duct or passage 7 0, leading to the pipe 4, said port and passage constituting the communication between the pipevalve and the organ-pipe through which the wind is admitted when the pipe-valve is open.

In Fig. 5', wherein a still different construction is shown, the body of the pipe-valve is designated by 11, and it is provided with the outwardly-projecting flange 13 and is shaped to present the stem 31, which extends through the wall 32- of the wind-chest 30. The cap ofthe' valve is designated by 14,

' and its walls 1,5 overlie the flange 13 and the edges of the dia hragm 8 are confined between the walls 0 the cap and the flange 13*, as in the other embodiments of the invention; In this embodiment the stem 31 is divided transversely by a suitable partition 37 .to form an air-supplypassage 16 and another passage 38,- which communicates, by means of a port 19, with a duct 7, leading to the pipe 4. The stem 31" of the valvebody projects into the pipe-valve, and the lower edge 17 a of said projecting end and the front edge of the partition 31 constitute a valve-seat against which the diaphragnrS seats. 18 designates the pipe leading to the pneumatic. In this embodiment of the invention the edges of the walls 15 of the cap are provided with some yielding packing ma' terial 39such, for instance, as leather or chamois and the edgesof the diaphragm 8 are confined between the covered edges of the walls 15 and the flanges 13 The frictly-diiferent construction phragm against its seat.

tion between the covering 39 on the edges of the cap and the material of the diaphragm is sufficient to hold the cap is place, although,

if desired, the means shown in Figs. 1 and 4 may be employed for this purpose.

In all of the embodiments of my invention it will be noted that the valve is metallic and that the valve-chamber is divided transversely into two compartments by the diaphragm and that the said valve is provided with a tubular member which projects into the valve-chamber and terminates in a valveseat against which the diaphragm seats. By making parts of the valve of metal all danger of leaks due to changes in hygrostatic conditions of the atmosphere is avoided. Further, in each embodiment of my invention the cap is made detachable from the body portion, and since each valve is a separate member or element it will be seen that the cap of any one particular valve may be removed without disturbing any of the other valves. This is important, because it provides for the repair of one valve or its adjustment without disturbing in any way any of the other valves.

, In some embodiments of the invention herein shown the cap is held in position on the body portion by a retainer, and in other embodiments the cap is detachably held by means of screws or by friction.

The operation of the valve will be readily understood by those skilled in the art. Normally the valve of the pneumatic controlling the pipe-valve is so arranged that wind-pressure is admitted to the compartment 9, this wind-pressure being sufficient to hold the dia- When it is desired to cause any pipe 4 to speak, the pneumatic controlling the corresponding pipe-valve is I operated so as to relieve the pressure in the chamber 9 of said valve, whereupon the pressure in the wind-chest 3 lifts the diaphragm from its seat, and thus opens communication between the pipe and wind-chest.
